Shenzhen, GuangdongAges 18–75 - NCT04434040RecruitingPhase 2
Atezolizumab and sacituzumab to prevent breast cancer return
This trial tests two medicines after surgery and chemotherapy to help lower the risk that triple-negative breast cancer comes back. It’s for people whose cancer still showed “residual” invasive disease after neoadjuvant (before-surgery) chemotherapy, and whose blood test shows traces of tumor DNA.
San Francisco, CaliforniaAges 18 years+ - NCT04437160RecruitingPhase 2
Chemo after surgery for triple-negative breast cancer with leftover tumor
This Phase 2 study tests chemotherapy given after surgery for people with triple-negative breast cancer who still have cancer left after initial (neoadjuvant) chemo. It may help lower the chance the cancer comes back in people at higher risk based on leftover tumor and lymph node findings.
Beijing, Beijing MunicipalityAges 18–75 - NCT04457895Recruiting
Yoga and physical therapy program for hormone therapy breast cancer pain
This trial studies whether a combined physical therapy, yoga, and patient education program can reduce pain in people with non-metastatic breast cancer who are taking hormone therapy. It may help with pain and day-to-day comfort while you continue hormone treatment.
Libourne, AquitaineAges 18–99 - NCT04469296Recruiting
Diet changes before surgery for hormone-receptor breast cancer
This trial tests whether changing your diet before your breast surgery can help people with early, hormone-receptor (ER/PR+) breast cancer. It focuses on patients who have not started treatment yet and want to keep surgery as the main treatment.
Montpellier, HeraultAges 18–80 - NCT04472845Recruiting
Shorter or longer breast radiation after surgery for high-risk cancer
This trial compares two schedules of radiation after breast surgery in people with high-risk, node-positive breast cancer. The goal is to see whether giving radiation in 1 week or 2 weeks works well and is safe after standard treatments.
ChandigarhAges 18 years+ - NCT04486495Recruiting
Minimally invasive lymph node treatment after chemo for node-positive breast cancer
This study looks at a less invasive way to check and treat lymph nodes in the armpit after you receive chemotherapy (and sometimes immunotherapy) before breast surgery. It may help people with cancer that has already spread to armpit lymph nodes by improving how staging and treatment are done.
's-HertogenboschAges 18 years+ - NCT04501419Recruiting
Mobile ultrasound test to help diagnose breast cancer
This study checks whether a tablet-based ultrasound can find breast lumps that look suspicious for cancer. If it works well, it could help diagnose breast cancer faster in Nigeria where patients may need a biopsy or surgery next.
Ile-IfeAges 18 years+ - NCT04523857RecruitingPhase 2
Abemaciclib and hydroxychloroquine after breast cancer relapse risk
This Phase 2 trial tests whether abemaciclib plus hydroxychloroquine can kill tiny “leftover” cancer cells in the bone marrow after standard breast cancer treatment. It may help lower the chance of cancer coming back by targeting minimal residual disease.
Philadelphia, PennsylvaniaAges 18 years+ - NCT04526587Recruiting
Study of breast cancer markers after CDK4/6 inhibitor treatment
This study looks at lab markers and clinical features in people with certain types of breast cancer who are being treated with, or have already been treated with a CDK4/6 inhibitor like abemaciclib (ciclib-based therapy). It aims to understand patterns that may help doctors better characterize breast cancer after these treatments.
Buffalo, New YorkAges 18 years+ - NCT04529044RecruitingPhase 2
177Lu-DOTATATE for advanced breast cancer with targeted receptors
This Phase 2 trial tests whether 177Lu-DOTATATE can slow or shrink stage IV or recurrent breast cancer. It targets tumor “receptors” found on scans, using a radioactive medicine that delivers radiation directly to cancer cells.
Portland, OregonAges 18–100 - NCT04543799Recruiting
Sleep quality study in prostate and early breast cancer patients
This trial studies how sleep quality changes while people with prostate cancer or early breast cancer receive standard treatments. It may help doctors understand which treatment factors affect sleep and identify who might benefit from support for sleep problems.
BellinzonaAges 18 years+ - NCT04553770RecruitingPhase 2
Trastuzumab deruxtecan with or without anastrozole for early breast cancer
This Phase 2 study tests whether trastuzumab deruxtecan alone or combined with anastrozole can control early-stage breast cancer that is HER2-low and hormone-receptor positive. It aims to improve outcomes after initial surgical treatment by targeting cancer cells that may have low levels of HER2.
Fullerton, CaliforniaAges 18 years+ - NCT04563507RecruitingPhase 2
Immunotherapy plus hormone therapy for metastatic ER-positive breast cancer
This Phase 2 study tests a combination of immune-based treatments along with hormone (endocrine) therapy to slow or shrink advanced, hormone-receptor positive, HER2-negative breast cancer. You may be a candidate if your cancer has progressed after standard hormone-blocking medicines and you can start treatment with CDK4/6 medicine plus an aromatase inhibitor.
